Applicationvled February 28, 1927.2 ScriaINo. 171,675.

My invention relates to a retaining valve` bracket of the type in whichthe valve isvattached to an auxiliary member movable independently ofthe bracket proper and consistsvin various novel features of construetion and operation.

In the accompanying drawings, which illustrate some forms of bracketVmade in accordance with my invention, Figure 1 is a 1U top plan view ofone form of bracket, to-` gether with a portion of a railway car towhich it is attached, and a retaining valve which it carries; Figure2 isa section taken on the line 2-2 of Figure 1; Figure 3 is a top planview, partly in section, showing a slight modification; Figure 4 is atop plan view showing a further modification; Figure 5 is a side view ofthe form shown in Figure 4; and Figure 6 isa section taken on the 3Uline 6 6 of Figure 4.

Referring iirst to Figures 1 and 2, 7 indicates the end of a. car towhich the bracket is attached. The body or iixed part of the bracketconsists of a plate of metal bent to form ends 8, a pair of forwardlyprojecting walls 9 and a central part 10. Rivets 11 .fjecure ends 8tothe car. Formed in the walls 9 adjacent to the central part 10 areslots 12 through which passes a strap 13l the ends 5", of which projectbeyond the Walls 9 and are provided with bolt holes 14. Bolts 15, ypro`vided with heads 16, pass through the holes 14 and through holes in thelugs of the retaining valve 17 which isV held in position by nuts 18 onthe bolts.

The holes 14 in the strap are somewhat larger than the bolts to give thenecessary adjustment for variations between the holes in the valve lugsand are in such relation to the walls 9 that these walls prevent therotation of the bolt heads. Vertical'adjustment is provided by themovement of the strap in the slots 12.

In Figure 3 I have shown a slight modiiication. This construction is thesame as that above described except thatl the straight` strap 13 isreplaced by a strap 19 having a pair of bends 20 to prevent the removalof the strap from the slots. stood that one or both of the bends must beformed after the strap is in position in the slots. In addition topreventing the removal of the strap from the slots the bends may be sopositioned with relation to the bolt holes It will be under-rV that theywillprevent the rotation of the bolt Aheads vand hence the walls 9 neednot be relied upon for their purpose and may, if

desired, bel situatedat wsomedistance from the bolts.'A y r l Figures 4,5 and 6 show a further modication. formed in the walls 9 but the centralpart 10 is provided with extensions 21'to which a second plate 22V issecured by rivets 23. The central part 24 of this plate 22 is bent outofthe plane of the ends so'that a space is formed between the parts 10and 24 to receive thestrap 10 which may in this construction have thebends 2O formed therein before the parts are assembled.

Having fully described my invention, what I- claim as new and desire tosecure by Letters Patent of the United States is:

1. In a device of the class described, the combination with a bracketadapted to be vsecured to a car and having a part spaced therefrom, ofan auxiliary member movable relatively to said bracket and projectingbeyond said spaced part, and bolts extending through the projectingparts of said auXil* iary member and engaging a retaining valve.

2. In a device of the class described, the combination with a bracketadapted to be secured to al car and having a part spaced therefrom, ofan .auxiliary member movable relatively to said bracket and projectingbeyond said spaced part, means for preventingvthe removal of saidauxiliary member from the bracket, and bolts extending through theprojecting parts of said auxiliary member and engaging a retainingvalve.

3. In a device of the class described, the combination with a bracketadapted to be secured to a car and having a part spaced therefrom, of anauxiliary member movable relatively to said bracket and projectingbeyond said spaced part, said auxiliary member being provided with bendspreventing its removal from the bracket, and bolts extending through theprojecting parts of said auxiliary member and engaging a retainingvalve.

4. In a device of the class described, the combination with a bracketadapted to be secured to acar and having a part spaced therefrom, of astrap movable relatively to the bracket and projecting' beyond thespaced part, said strap having bolt holes in In'this construction noslots are the projecting part, and bends adjacent to the bolt holes to-preventrotation of bolt heads.

5. In a device of the class described, the combination With a bracket,of a plate secured to said bracket and haying'its central part spacedtherefrom, an auxiliary member in the space between said bracket andkplate and projecting beyondthe latter, and bolts carried by saidauxiliary member and adapted to engage a retaining valve.

6. In a device of the class described, the combination with a bracket,of afplate secured to said bracket and having its central part spacedtherefrom, a strap vin the space between said bracket and plate andprojecting beyond the latter, bolt holes in the projecting ends of saidStrap, and bolts in said holes adapted to engage Ya' lretaining valve,SaidV strap being)- provided with bends ad- Ajacent to the bolt holesrto engage the bolt I hereunto aliix my 30
